OIL-BURNER.

SPECIFCATION forming' part of Letters Patent No. 15,227, dated December2, 1902.

Application tiled March 13, 1902.V Serial No. 98,815. (lio model@ To @ZZwhom t may concern,...-

Be it known that I, FRANK N. VILOQX, a citizen of the United States ofAmerica, residing at New Orleans, in theparish ot' `Orleans and State ofLouisiana, have invented certain new and useful Improvements in Oil-Burners; and l do hereby declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilledinY the art to which it appertains to make and use the same.

My invention relates to improvements in oil-burners; and it consists inproviding a suitable oil-burner in which the oil is distributed by andconsumed from the surface of water.

The invention also consists of certain novel features which will behereinafter described and claimed. l

Reference is had to the accompanyingdrawings, in which the salue partsare indicated by the same letters throughout the several views.

Figure l represents a plan view of a burner, part of the cover beingbroken away. Fig. 2 represents a section along the broken line 2 2 ofFig. l and looking in the direction of the arrows. Fig. 3 is an invertedplan View of the annular perforated plate used in the burner, and Fig. 4represents a section-along the line 4 4L of Fig. l and looking in thedirection of the arrows.

Arepresents the shell or body of the burner, which is provided with aflange A', having a vertical ring d. Between the body of the burner andthis vertical ring are a number of ribs A2, radially disposed, whichribs are V-shaped, as shown in cross-section in Fig. 1, to form V-shapedtroughs d2, with interposed air-passages a3. These V-shaped `troughs a2open into the liquid-chamber in the bottom of the burner, as shown tothe left of Fig. 2.

Through the centerof the body A, l provide a hollow cylinder A0,projecting above the surface of the liquid, as shown in Fig. 2. Thiscylindrical opening allows a passage upward therethrough of air, andthus prevents excessive heating of the liquid contents of the burner andalso supplies air to the burningsurface of the oil.

B represents an annular scattering-plate which slips over thiscylindrical center of the somed.

burner-body and rests on a shoulder a. This annular plate is perforated,as at b, the said perforations being conical in theform of invertedfunnels for the better scattering of the oil and water passingtherethrough.

Oil is fed into the base of the burner through a pipe C from anysuitable source of supply, and water is pumped into the base of theburner through the pipe D. lf it be desired to wash out the burner, thevalve ol may be `closed and the contents ofthe burner may be drawn olfthrough the waste-pipe D.

E represents a cap, perforated as at e, which covers the center of theburner and serves to deflect outward the air passing up through thecylindrical aperture A", at the same time to contine the combustion tothe annular space outside ot said cap and above,

the V-shaped troughs a2. omitted, if desired.

F represents a pipe to carry ot the liquid contents of vthe burner abovea certain level, which may be used when the oil and Water become toointimately mixed, it being preferable to have the oil mainly lioating onthe topof the Water at the time it is being con- Bydrawing oft the oiland Water through the pipe F above the level of the orilice ol' saidpipe fresh oil and water may be injected through the pipes C and D, andthus the proper proportions and admixture may be secured. A

The supply of oil and water may be regu- This cap may be 4lated byvalves controlling the pipes C and D or in any other convenient Way.

The operation of the device is as follows: Oil and Water are fed inthrough the pipes C and D and rising together, the oil principally abovethe water, will pass through the opening d upward beneath the cap E.Thence spreading laterally the oil and Water will flow into the V-shapedtroughs a2, and the oil be ing ignited by a smallpiece of Waste soakedin oil or in any other convenient Way coinbustion isstarted. Air risesthrough the inlets as and supplies the necessary .oxygen to convert thecarboniccoxid of the-llameinto carbon dioxid and to ca'use perfectcolnbustion. The air coming up through the central passage A0 serves toprevent the liquids in the burner from becoming toorhot prior tocombustion ,thus preventing the evaporation IOOofan-excessiveamountofwater. At thesame time some of this air passesunder the edges of the cap and over the oil in the V-shaped troughs,thus further aiding in thecombustion.

While burning, the air evaporates more or less of the water, and thesteam so formed in passing through the boiler or over the other objectto be heated gives up a large part of its heat. The water thus not onlyserves as a medium for finely distributing the oil over a wide surfacefrom which surface the oil is consumed, but it also serves to lessen theintense heat of the burning oil, which is objectionable inmost of theuses to which such burners are applied.

By the herein-described apparatus complete combustion of the oil issecured, and a cheap, sim ple, and effect-ual apparatus is provided inwhich the desired result is economically obtained. Y

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

1. An oil-burner comprising an annular chamber with air-passage throughthe center thereof, the said chamber having a narrow base and auenlarged upper portion provided with a series of radial troughs toreceive the liquid, with air-passages between said troughs, with meansfor simultaneously feeding oil and`water into the base of said chamber,whereby the oil is caused to pass through and spread out over thesurface of the water in the enlarged portion of said chamber,substantially as described.

, 2. An oil-burner comprising an annular chamber with air-passagethrough the center thereof, the said chamber having a narrow base and anenlarged upper portion, provided with a series of radial troughstoreceive the liquid, with air-passages between said troughs, with meansfor simultaneously feeding oil and waterinto the base of said chamber,whereby the oil is caused to pass through and spread out over thesurface of the water in the enlarged portion of said chamber and ascattering-plate arranged in said chamber below the normal surface ofthe oil, substantially as described.

3..An oil-burner comprising an annular chamber with an air-flue throughthe center thereof, the said chamber having a narrow base and auenlarged upper portion provided with a series of radial troughs toreceive the'liquid, with air-passages between said troughs, a cap abovesaid air-flue and extending over the inner ends of said troughs, andmeans for simultaneously feeding oil and Water into the base of saidohamber,whereby the oil is caused to pass through and spreadout over thesurface of the water in the enlarged portion of said chamber,substantially as described.

4. An oil-burner comprising an annular chamber with an air-flue throughthe center thereof, the said chamber having a narrow base and anenlarged upper portion, provided with a series of radial troughs toreceive the liquid, with air-passages between said troughs, a cap abovesaid air-flue and extending over the inner ends of said troughs, andmeans for simultaneously feeding oil and water into the base ofsaid'chamber, whereby the oil is caused to pass through and spread outover the surface of the water in the enlarged portion of said chamberand a scattering-plate arranged in said chamber below the normal surfaceof the oil, substantially as described.

5. An oil-burner provided with a central chamber, with radial troughsexterior to and connected to said central chamber, air-passages openingupward between said troughs,

a cap above said chamber and extending over the inner ends of saidtroughs, and means for supplying oil and water to the base of saidchamber, substantially as described.

6. An oil-burner provided with a central annular chamber with a verticalair-passage therethrough, radial troughs exterior to and connected tosaid central chamber, air-passages opening upward between said troughs,a cap above said air-flue and extending over the inner ends of saidtroughs, and means for supplying voil and water to the base of saidchamber, substantially as described.

7. An oil-burner provided with a central annular chamber with a verticalair-passage therethrough, radial troughs exterior to and connected tosaid central chamber, air-pas.- sages opening upward between saidtroughs, a scattering-plate below said troughs, a cap above said air-dueand extending over the inner ends of said troughs, and means forsupplying oil and water to the base of said chamber, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
